Question

f(x)= x-1
g(x)= -2x+5
how to solve this by graphing it?

Answer 1

I assume you know how to graph the individual lines.

Since the solution (x,y) satisfies both functions, the point of intersection of the lines is the solution.

Answer 2

(2,1)

Answer 3

thanks !!

Answer 4

Which you can check by just putting the functions equal to each other

x-1 = -2x +5 -> x= 2 etc.

Answer 5

aha i think i got it thanks again !
